GYROSCOPIC STEERING DEVICE.

Patented July 4, 1916.

Application filed August 9, 1915. Serial N 0. 44,513.

T 0 alt-whom it may concern Be it. known that I, OTTO K. CAZIN, a citizen of the United States, residing at the city 7 of Newark, in the county of Essex and State termined time afterthe firing of the torpedo from the tube, and also for alining the said second gyroscope with the first gyroscope,

so that the torpedo will continue on a- V. la nge, to hold more truly to the line of aim than is possiblewith the present gyroscopic straight course or turn to some predetermined angle at somefixed point In its course,

transferring of the steering function from the first gyroscope to said second gyroscope.

The objects of 'my improvements are, firstto cause the torpedo when fired at long steering mechanisms, and, secondlyto provide a means for turning the torpedo through some predetermined angle at some predetermined point of its course.

It is a well known fact that the gyroscope whenfirst fired and running at high speed will hold the torpedo true to the line of aim, but as the speed of the gyroscope wheel diminishes, it becomes less accurate in hold-- in the torpedo to the true line. It is the fobject of the second gyroscope to start at high speed and take over the steering function when approximately half the range has i been run and when the first gyroscope is approaching an unreliable speed; and by means of this transfer to carry the torpedo true to the mark. work, it would be possible'by means of this mechanism to use any desired number of gyroscopes.

Gyroscopic steering devices as at present constructed allow the torpedo to be turned through some predetermining angle at the start of their run, but by means of the second gyroscope together with the starting and alining mechanism it is possible to turnthe torpedo through a second predetermined angle at any desired point of its course This function would be of value in firing i In extremely long range.

the stern of a ship directly ahead, as the torpedo would not approach the ship in a direct I line and through the water'thrust .from theships propellers. but could approach at one side, and by turning the second angle at the proper time turn to attack the ship broadside on.

It is not my intention to claim any im-- bal ring C by the bearings C. the outer gimbal ring being held in the frame (Z by the bearings al The spinning nozzle is shown at d and the seat and air connection at (i and the locking lever at d; the tripper is shown at e, the plate at e with the re ciprocating lever at e?, and its shaft and gear wheels at 6 e and c, the main torpedo driving shaft being 6?. All these parts are made according to standard practice, and as no improvement is intended therein, a moredetailed description of their functions is omitted.

The invention and improvement claimed consists in the addition of the gyroscope B together with the mechanism shown, in which f, f F, f and f are in this case a train to gears driven from the main shaft This train of gears is shown for convenience in the drawing, a longer train. of gears being actually required and could consist of ftjh The pin 11, is attached to the le-. a Pa r gh. a holegn roscope easing (l. The hole It in the outer -gil nl)al ring (l is placed sothat whenthe axis of the gyroscope wheel is parallel to V -";t he longitudinal 'cen'ter line ofthe torpedo 5 thenthe hole It and the-pin IE will register. The leverh is drawn'upufard by-the spring ]r*- which holds the lever against the projed tion g and when the .lever has fallen from the end- .of the spring presses the pin I 9 10 lightly against thegimbal ring C'until the hole l1), comes'into position when the pin enters.the hole unless prevented from doing so by otheraietious which will presently be described], The lever h is also connected to an air-valve Gin which k is-the piston and (f-' is the casing having the ports g g and g. The port'{/ is connected with the air supply and the port g is connected to the spinning and unlocking mechanism of the '20 g \-'rosc0pe' B through the nozzle (i i; "The port is connected to'the steering engine of the torpedo in such amanner that when the rudders are at oneside of the torpedo the air pressure 'will be "communicated 2 5 through the port 1 ontoithe' piston "and- "will prevent-the piston from rising under the-influence of the spring 'hfl-butif on the contrary the rudders ,are on {the opposite side of the torpedo therewill be no pressure .30 onthe piston-and thelerer b will be free to rise' and" the pin h can enter *the hole h when they come .in line. The object of this regulationl w-itli regard to the rudder is that thepin h can only enter the hole h when 5 the torpedo is turning iii-one direction and the second gyroscope B can, therefore be set'soas" to compensate for the angle turned duringthe-tiine it takes for thesecond gy'roscope tobe spu nand to take over the steer-- 40 mg function; hen the pin h" has entered the hole 11, the piston 9 assumes a position:

such as to allow the air to pas's ifrom g to g and thus to spin the second gyroscope B and cause it to be unlocked and to take. over the steeringfunction;the air pressure from 'g" at'the same time passing-to the second steering engine and also operating a valve cutting off the th'st,steering gf. engine;
